Get Magnesium Online
Muscle cramps, fatigue, and irregular heartbeat can all signal low magnesium. Doctronic connects you with a licensed physician who can evaluate your levels and prescribe the right magnesium supplement to restore balance and support your body.
What Is Magnesium?
Magnesium is a prescription-strength mineral supplement used to manage magnesium deficiency (hypomagnesemia) and to support normal muscle, nerve, and cardiovascular function. It works by replenishing intracellular and serum magnesium levels, which are required as a cofactor in over 300 enzymatic reactions including energy production, protein synthesis, and electrolyte transport. With the right dose and ongoing monitoring, most patients experience meaningful relief from deficiency symptoms and improved overall wellbeing.

Is Online Magnesium Treatment Right for You?
You may be eligible for a Magnesium prescription if you have been experiencing symptoms of magnesium deficiency, such as muscle cramps, weakness, fatigue, tremors, or abnormal heart rhythms, or if lab work has confirmed low serum magnesium levels. Patients with dietary insufficiency, malabsorption conditions, or chronic use of diuretics or proton pump inhibitors are also commonly evaluated for supplementation.
Because magnesium plays a critical role in cardiovascular and neuromuscular function, your physician will review any relevant history involving kidney disease, heart conditions, or current medications that may affect magnesium absorption or excretion before prescribing.

Frequently asked questions
Magnesium deficiency, or hypomagnesemia, occurs when the body does not have enough magnesium to support normal cellular function. It is estimated to affect a significant portion of the general population, particularly those with poor dietary intake, gastrointestinal disorders, diabetes, or chronic use of certain medications such as diuretics and proton pump inhibitors.
Common symptoms include muscle cramps or spasms, persistent fatigue, weakness, tremors, numbness or tingling, irregular heartbeat (palpitations), and difficulty sleeping. Severe deficiency can lead to more serious complications such as cardiac arrhythmias and seizures.
Diagnosis is typically made through a blood test measuring serum magnesium levels. A result below 1.7 mg/dL is generally considered low. Your physician may also evaluate symptoms, dietary habits, and other lab values such as calcium and potassium, which are often affected alongside magnesium.
Magnesium glycinate is chelated with the amino acid glycine and tends to be gentle on the stomach with high absorption. Magnesium citrate is well absorbed and may also promote bowel regularity. Magnesium sulfate is typically reserved for more acute deficiency and may be administered intravenously in clinical settings or taken orally under close medical supervision. Your physician will recommend the best form based on your individual needs.
Yes. Long-term use of proton pump inhibitors (such as omeprazole), loop and thiazide diuretics, and certain antibiotics can deplete magnesium levels over time. If you take any of these medications, your physician may recommend monitoring your magnesium levels regularly.
Magnesium is primarily excreted by the kidneys, so patients with impaired kidney function face a higher risk of magnesium accumulation and toxicity. Your physician will carefully evaluate your kidney function before prescribing and will adjust the dose accordingly. Self-supplementing with magnesium is not recommended for patients with kidney disease without medical supervision.
